life support and PCS exp date?

how do i tell when the bottle expires? i just got my order in of BOGO life support and post cycle support. 1 PCS has nothing on it while the other says "9-11". that one i can easily assume expires on that date. but my life support says " PO111209" so does that mean it expires 11-12-09?

PO111209 means it was Produced On 11/12/09 and is still at full potency 2.5 years later. It sounds like the other bottle's sticker came off. PCS has only be in production for less than 2 years so you are fine.
